April 24, 1940, Nos. 7408/40 and 6274/41. [Class 83 (i)] In casting a hollow steel or other ingot, the core comprises a shell 4 and a pillar 5, the space 6 between these being supplied with fusible metal or alloy from a cavity in the core by applying pressure to the metal in the cavity. A pot 22 charged with molten fusible metal may be lowered through the shell 4 on to a block 19 supported by a box 20 from the base 2 of the mould 1. The pillar 5 carried by its threaded part 13, screw 10 and bridge 12 is then inserted in the shell with its lower end above the level of the metal in 22 and the bridge resting on the head 3. The pillar is then lowered by rotating the screw by gearing in a box 11 and handle 15 to cause the metal displaced to rise in the shell as the steel rises in the mould. Fusible metal flowing between the shell 22 and block 19 is frozen by a blast of air 26 and the level in the shell is indicated by a pressure gauge connected to a pipe 29 connected to a small supply of compressed nitrogen or carbon-dioxide. To remove the casting the fusible metal around the block 19 may be melted by a hot blast 28. The lower end of the pillar may be preheated or insulated. In a modification, the pillar is stationary and the fusible metal is forced out of the pot 51, Fig. 2, by compressed gas supplied to a bell 52 submerged therein, the pressure, indicated on a gauge 76, being a measure of the level of the fusible metal in the space 6. The pot may also contain oil, gas, electrical or other heating means 63 and electrical heat-indicating means 77. The base 2 may contain steel splash wells 81 arranged directly below the poured streams of metal, leaden linings 82 being provided to prevent strain during cooling. The upper part of the shell 4 may be screened by a shield 9 and the lower part with a valved discharge duct. Specifications 376,405, 520,598 and 582,847 are referred to.

As shown, rotor 1 is suported and driven by known (not shown) means. A normally stationary pipe 5 enters, through an opening 6, an acceleration chamber 7. A dividing plate 8 is furnished with an open annular channel 9 which is connected with the open ends of, in this case, five porous spirally extending pipes 10, which occupy coaxially and in mutual concentric arrangement an internal rotor chamber 11, and whose opposite open ends are connected to an annular expelling chamber 12. The internal rotor chamber 11 is also in connection with a normally stationary pipe 13, which as shown is co-axial with the hollow shaft 3, but alternatively may be inserted through the opening 6 and inside and concentric with the pipe 5 and penetrating the plate 8 in any suitable manner. In that case the shaft 3 may be solid, and the means 4 for the removal of fluids is eliminated. Rotor chamber 11 is connected to the outer atmosphere either through radial channels 14 or through parallaxial channels 15 which may be placed at different distances from the axis of rotation. Expelling chamber 12 is connected to the outer atmosphere through peripheral channels 16, or to the hollow shaft 3 through channels 17. In a ro process the permeate leaves the rotor chamber 11 through channels 14. In a dialysis process the channels 15 are used to expel water or a diluted solution which has acted through the porous pipes and the spm lining against a concentrate flowing inside the pipes. The opening 6 may be' sealed with a gasket 18 against the pipe 5. The hollow shaft 3 may contain gaskets to seal against the pipe 13. The disc 8, pipes 10 and a lower dividing disc 19 may form one unit which can be inserted into the rotor 1 without special tightening means but with some elastic gaskets 20 which press against the rotor's inner surface.

Title: Continuous casting of steel
IPC: B22D11/11
Filed: 1961-03-02
Abstract: 919,257. Continuous casting - machines. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. March 2, 1961 [March 24, 1960], No. 7606/61. Class 83 (1). The thickness of the compact outer skin of a continuously-cast ingot of effervescent steel is continuously measured and the rate of addition of deoxidant to the liquid metal in the mould is controlled in accordance with this measurement so as to cause the formation of a skin of predetermined thickness. The measurement of thickness may be performed by passing radiations such as gamma rays through the ingot and comparing the intensities of the incident and emergent rays, the absorption of the radiations being affected by the presence of blow-holes in their path. The addition of the deoxidant, e.g. aluminium may then be regulated manually or automatically in dependence on a signal generated by the radiation detector. The deoxidant may be supplied in solid form, as granules or aluminium wire from a bobbin, or in liquid form as from a gas-tight furnace 9, Fig. 15, the feed being regulated by controlling the gas pressure applied above the surface of the molten aluminium through a duct 17.

Title: Improvements relating to actuating devices for guards for presses and analogous machines
IPC: F16P3/04
Filed: 1922-03-16
Abstract: 199,141. Hordern, A. W., (trading as Hordern & Mason). March 16, 1922. Guards, controlling.- In actuating- means for guards for presses, stamping- hammers, &c., motion is transmitted from a moving part of the machine to the guard by hydraulic or pneumatic pressure or by vacuum, so that, by employing flexible piping, the guard can be applied as a unit to various types of presses &c. As applied to a press guard, Fig. 1, a shield 10 slides on guide-bars 9 carried in a frame 8, and is connected to a piston in a cylinder 17, which is screwed into the frame 8 and communicates by a flexible pipe 16 with a pump cylinder 14. The cylinder 14 is mounted on trunnions, its piston-rod 13 being connected to a pivoted arm 5, which has a cam-surface or slot 4 adapted to be engaged by a pin 3 on the ram 2. The shape of the camsurface or slot 4 and the relative sizes of the cylinders 14, 17 are such that the guard is moved to, or almost to, its final position during initial descent of the ram. In an alternative form, the rods 9 are carried by the guard 10 and slide in the frame 8. In a modification, the guard member may be carried by or constituted by lazy-tongs, as shown in Fig. 4. The end links 64 are pivoted to the actuating piston-rod 19 and to collars 36 slidable on fixed vertical rod 37, and the end links 38 are pivoted to sliding collars 40 on a rod 41 slidable on guide-bars 43. Fig. 4 shows also an alternative method of connecting the pistonrod 13 to the arm 5 by a pin-and-slot arrangement 60, 61, where the cylinder 14 is fixed. In both constructions, the guard may have a padded leading edge 25, spring buffers 24 may be provided, and the guard may be retracted by fluid action alone or by a spring, such as 22, Fig. 1. A relief cock 21 may be fitted on the cylinder 17, whereby the guard may be stopped, or the length of the fluid column, and hence the relative positions of the guard and ram, may be varied. A pistoncontrolled exhaust port may be provided in the cylinder 14, so that the first part of the pump stroke may be idle, and a similar port may be provided in the cylinder 17, in order to limit the travel of the guard. A double guard expanding in both directions from a central bracket may be used. In place of the pin-actuated lever 5, an arm on the driving crank-shaft may be connected to the rod 13. According to one of the Provisional Specifications, the exhaust port in the cylinder 17 functions to enable the guard to be fully actuated during the initial descent of the ram when there is no lost motion between the piston-rod 13 and the moving part of the press &c. to which it is connected; the piston-controlled port in the cylinder 14 allows the pressure or vacuum to become normal before the succeeding stroke.

Abstract: 230,640. Cronkshaw, A. F. March 27, 1924. Parlour games.-Apparatus for use in playing games of skill comprises means for flinging a freely-suspended ball against externally mounted objects, the said objects being in the form of figures having movable and controllable parts. A ball c, Fig. 2, is suspended over the centre of a circular table a, at such a height as to contact with a rotating wheel i, the serrated edge of which causes the ball to fly outwards and strike the heads of figures b. The head of each figure is pivoted on a spindle -r, Fig. 4, and upon being struck by the ball, rotates in a rearward direction against the action of a spring-pressed lever t<1> which normally holds it in position. The arms of each figure are pivoted and may be raised to guard the head by means of a lever under the control of a player. The operating rod y for the arms may be provided with a projection 18 adapted to engage the end t of the rod t<1> and thus prevent the rotation of the head while the arms are in raised position. To prevent the arms being held constantly in raised position, the rod z, Fig. 8 connecting the rod y to the operating lever is formed in two parts 6, 7 provided with engaging jaws 6<1>, 7<1>. As the rod 7 moves in the direction of the arrow the rod 6 moves up a slope 9 and is drawn out of engagement with the rod 7. The rod 6 returns along the upper side of spring-pressed flaps 11 under the action of a spring or the weight of the arms, the movement being retarded by a dash-pot 1. In a modification, the rotating wheel i is replaced by a series of radially movable plungers actuated by a central revolving cam. According to the Provisional Specification the arms may be electrically operated, and the figures pivoted at the bases.
